What Is Lightning Crotch in Pregnancy?

Pregnancy can bring unexpected physical changes. One surprising symptom during pregnancy is frequently known as ‘lightning crotch’, which may cause sudden, sharp pains in the pelvic, vaginal, or rectal area. Read on to learn more about lightning crotch and other aches and pains in that area, what causes them, what they feel like, and how to help relieve the discomfort.

What Is Lightning Crotch?

‘Lightning crotch’ isn’t a medical term, it’s actually a colloquial phrase used by some pregnant people to describe sharp, sudden pains that occur in the pelvis, rectum or vaginal area during pregnancy. There isn’t a precise definition for lightning crotch, but you could think of it as a discomfort that's possibly related to other aches and pains during pregnancy.

What Does Lightning Crotch Feel Like?

Lightning crotch, as well as other aches and pains in this area, may vary in intensity from person to person – everyone experiences pain differently, and it’s not always easy to pinpoint exactly where the pain is coming from.

Some people describe ‘lightning crotch’ as feeling like a shooting pain or a bolt of lightning in the vaginal area, hence the name. However, pains in this region (including the pelvic area, hips, crotch, vagina, lower back, and abdomen) may range from mild discomfort or pressure that comes and goes sporadically throughout pregnancy to painful and intense sensations with sharp or jabbing pains that can occur suddenly and last for several minutes.

It's important to contact your doctor or midwife if you’re experiencing something like lightning crotch or any pain during pregnancy, especially if it’s constant or severe.

When Does Lightning Crotch Happen During Pregnancy?

The timing for any aches and pains that occur in pregnancy varies for each person. From early pregnancy to delivery, your body changes and adapts to your growing baby, so it’s normal to feel some pain (such as lightning crotch) from time to time.

In the second trimester, pain can occur in the lower abdomen and even into the hips and groin as your uterus expands and stretches the ligaments, and this may feel like lightning crotch.

As pregnancy progresses into the third trimester, it’s common to experience discomfort related to the growth of your baby and hormonal changes. Lightning crotch, lower back pain, or pelvic pain can occur; you may also feel pains in your hips and legs.

As you approach the end of your pregnancy, you might experience pains in your pelvic area, which may be associated with lightning crotch, as your body prepares for labour.

Remember, no matter what stage of pregnancy you’re in, if you experience pain, it’s best to contact your doctor or midwife for a diagnosis.

What Causes Lightning Crotch During Pregnancy?

Though the exact cause of lightning crotch is not fully understood, it could be related to pelvic girdle pain (PGP), also known as symphysis pubis dysfunction (SPD), in which the joint at the front of the pelvis, the pubic symphysis, allows for more movement than usual. Too much movement from this joint can lead to pain in the pelvis and groin.

If you’re experiencing pain in this area, it’s best to contact your doctor or midwife to pinpoint the cause of the pain. The following are among the potential causes of pain in your pelvic and vaginal area during pregnancy:

• Pressure from the baby on the nerves in the pelvis as the baby drops into a deeper position in preparation for birth

• Your baby's movements in the uterus

• Hormonal changes during pregnancy that can affect the ligaments in the hips and pelvic area, making them looser and stretchy in preparation for birth (this form of hip and pelvic pain is also known as round ligament pain)

• Your body preparing for labour and delivery (It’s common to wonder if contractions can feel like lightning crotch. While both contractions and lightning crotch may vary from person to person, it’s important to read up on signs of labour to help you recognise the symptoms of lightning crotch vs contractions)

• A urinary tract infection or bladder irritation

• Ectopic pregnancy.

How to Help Relieve Lightning Crotch

Though the causes of lightning crotch are often unknown or hard to pinpoint, there are some measures you can take to help relieve this and other uncomfortable symptoms during pregnancy. Here are some examples, and your doctor or midwife may also make recommendations for your specific situation.

• Practice prenatal yoga or swimming to help strengthen and relax your pelvic muscles, and avoid exercises that cause pain.

• Take warm baths or use heat packs on the painful area for temporary relief.

• Apply a cold compress to the area for numbing relief.

• Avoid standing for long periods of time.

• Wear comfortable, supportive shoes.

• Avoid lifting heavy objects.

• Do Kegel exercises to strengthen your pelvic floor muscles.

• Wear comfortable, breathable underwear and clothing that doesn't constrict your pelvis.

• Use a pillow between your legs when in bed.

• Keep your knees together when turning over in bed or getting in and out of a car.

• Take short breaks throughout the day, such as lying down on your side for 15 minutes or taking a short walk to help relieve pressure.

• Get plenty of rest and stay hydrated.

It's important to contact your doctor or midwife right away if you're experiencing any persistent or severe pain during pregnancy.

When to Call Your Doctor or Midwife

If you're experiencing lightning crotch or something similar during pregnancy, it's important to remember that while it can be uncomfortable or even painful, it may not be a cause for concern. However, any persistent or severe pain should always be discussed with your doctor or midwife to rule out any potential complications.

If your vaginal pain (or lightning crotch) is accompanied by vaginal bleeding, fever, vomiting (not associated with morning sickness), or pressure in your pelvic area or lower abdomen, or if you experience signs of labour or preterm labour (if you’re less than 36 weeks pregnant) such as contractions or your waters breaking, contact your doctor or midwife immediately.

Remember, every pregnancy is different, and what may be commonplace for one person may be completely foreign to another.
